FUJI GLASS BEADS (FGB)

FUJI GLASS BEADS (FGB)
This spherical glass beads does not cut the surface more than necessary. It creates uniform pearskin surfaces
 It’s homogeneous, soda glass abrasive that is stable physicochemically. It does not cut processing surfaces more than necessary nor contamintate them, so it enables high-precision surface processing, and creates characteristic matte surfaces. Also it’s used for shot peening which prevents metal from fatigue breakdown or stress corrosion cracking, over a wide range. The processed surface is resemblant to that of a golf ball, showing gentle concavities and convexities. The more the particle diameter is big, the more the surface becomes glossy. Use application : Cleaning, post weld cleaning, before and after plating, adjusting sliding surfaces, deburring for powder metallurgy parts or aluminum die-cast products, cleaning molds for rubber / plastic / glass, deburring for gears, improving the resistance to fatigue, removing carbon deposition, pearskin finish for decorative purposes (digital cameras, notebook computers, etc.), deburring for injection needles, various surface finishing.
